Power Management problems

[Nathan England]

I have been running kernel 2.6.24.7 but I upgraded my processor and the 
thermal sensors changed, so I was forced to upgrade to 2.6.28.4. Everything is 
working now, even things that did not before, but powermanagement in kde is 
awful now!

The battery plasmoid nolonger notifies me of being ac powered or not, if I 
unplug the power none of the settings change.

What do systems to the power management features rely on? I would like to make 
sure I have everything in my kernel that needs to be there, or that something 
hasn't changed...?

Any hints? I have all the same APM and ACPI features built as modules that I 
did before, so I'm at a loss what might be causing this...

KDE 4.2.0 btw.
